4 claims. (ci. gas-z) f'Y This invention relates to dumping vehicles and l i- .hasvparticular application for use in cemeteries y where earth must be transported a considerable distance from an excavation to a dump heap.

- v 5 An object of the invention is to make a dumping vehicle which may be placed at the end or a grave so that ea'rth removed therefrom may be :thrown directly into the vehicle body, then trans- .ported over low grave markers to a road and then y flo,c onnected in a trainfor transportation to a remote point.

j A further object of the invention is to make a vehicle which has a frame that is suiciently rigid to support the weight of the load and yet is light `l5 .in.weight. Additionally, the invention includes a -tiitable body which may be turned `completely 1 :over within the connes oi the frame and which includes a latching device by means of which the body, will be locked in load-receiving position merely by turning it back at the completion of bodying my invention connected together in a train for transportation.

3 Designating the parts shown in the drawings by reference characters, the vehicle chassis comprises an open frame having side portions III and II and end portions I2 and I3 respectively.

The portions III and II may continue beyond the portion I2 and extend downwardly and terminate lin handles I5, and I6, respectively. The frame may be made of tubular members that are welded together and that are reinforced at the corners by plates Il, IB, I9 and 2Q respectively.

The chassis, in addition to the open frame, includes wheel receiving yokes, each of which may comprise an inverted U-shaped'tubular member indicated in general at 2l and 22, as being at- 45 tached, as by welding, to the frame side portions Ill and II respectively. The lower4 ends of the yoke arms are adapted to receive pins 23 and 24 which serve as axles for the wheels 25 and 26 respectively.- .'I'he connection between the yokes 50 and frame may be reinforced by struts 21 and 2B, each of which is shown as a U-shaped tubular member which extends diagonally upwardly from the arms oi the yokes 2| and 22 respectively and which also may be welded to the frame portions 55 I0 and II respectively. Additional bracing may be secured by struts 29 which extend diagonally from the inner leg of each yoke 2l and 22 to the frame.

The designated body 3l may comprise an open box, the bottom of which is pivotally supported I5 on a bar 35 -which extends transversely of the frame and is shown as being attached at its ends to the inner arms oi' the yokes `2i and 22 respectively. This connection may be reinforced by plates 36 and 31, which, as shown in Fig. 3, are l0 welded to the bar 35, to the frame portions IB and II, and to the inner legs of the yokes 2l and 22 respectively. 'Additional bracing may be obtained by plates 38 and 39, which may be similarly fastened to they under portions of the bar 35 15 and to the Vinner legs of the yokes 2l and 22 respectively. This assembly results in a chassis that is light in weight and yet has sufficient strength to permit the transportation of a load of earth across uneven ground without weaving or distortion o1' the frame.

In Fig. 2, the full lines 3l show the normal position of the body for receiving a load, whereas the broken lines 3|a illustrate the inverted position. 'I'he clearance between the ends of the 25 frame and the body is sumcient to permit the body to be pivoted about ythe bar 35 without disturbing the horizontal position of the frame. Moreover, the distance between the pivot and either end of the body is less than the distance so between the pivot and the ground, and hence, the load may be dumped while the vehicles are attached together in a train in a manner hereinafter set`1'orth. To facilitate the loading operation, the vehicle may be supported by resting the handles upon the ground as shown by the broken line position Ita in Fig. 2, at which time the body occupies the position shown by the broken line 3Ib in Fig. 2. C o

The vehicle illustrated herein isadapted to be connected in a train as previously set forth, and to this end, I have shown a clevis 40 on the end frame member I3 and I have shown an apertured rod 4I extending from the frame porl5 tion I2 for engaging a clevis on a coacting vehicle as shown in Fig. 44. To support the bar 4I, I may provide a cross-bar 42 which extends between the frame pieces I! and II and parallel to the end portion I2. The bars I2 and 42 may I0 then support a plate 43 on which are mounted brackets 44 and 45 respectively. The bar 4I may be loosely fitted within the bracket and held therein by means of a detachable pin 46 as shown in Figs. 1 and 2. This arrangement enables the 55 bar 4I to be removed whenever the vehicle is tilted to load-receiving position, and thereby to provide more clearance during the loading operation, or whenever the vehicle is used as a hand truck.

To hold the body in load-receiving or upright position, I have illustrated a locking device which may take the form of a latch 50 which is shown in the form of a plate that is pivoted at 5| in a bracket 52. 'Ihe bracket may be supported on a plate 53 which is shown as being fastened to the frame piece Il and to the reinforcing plate 31. A spring 54 normally urges the plate into the full line position shown in Fig. 3, Where it is adapted to engage a shoulder or notch 55 in an arcuate cam 56, which is attached to the one side of the body 3l.

Normally, the latch enters the notch 55 and holds the body in the load receiving position, but to release the body so that it may be inverted, the latch may be manually withdrawn from the notch. This may be done by lifting a handle 51 which is shown as being formed on a lateral extension of the pivot 5|. To facilitate the inversion of the body, I may mount it slightly off center upon the bar 35, but the same results can be accomplished in practice by loading one portion of the body more than another portion so that an unbalanced effect will be obtained. In this Away the tilting of the body is accomplished merely by lifting the handle 51 and thereby withdrawing the latch 50 from engagement with the notch 55.

`A vehicle made in accordance with the present invention is suitable for use in locations where it is necessary to clear low lying objects, such as grave markers which project about a foot above the ground. The vehicle is well suited for use either as a hand truck, or as a trailer, and in the latter use it is well adapted for connection in tandem with other similarly made vehicles. The latching device permits automatic tilting of the body, and accomplishes automatic locking whenever the body is returned to the load receiving position. In this way loads may be quickly dumped by the tractor operator without disconnecting the vehicles from the tractor or from each other..
